The New York Knicks knew that Jeremy Lin had a torn meniscus in his left knee but waited to reveal the extent of the injury until after the deadline for season-ticket holders to purchase playoff tickets, the New York Daily News reports.

That deadline was last Wednesday, March 28. The Knicks had the results of Lin’s MRI two days prior, according to the Daily News. An email sent to season-ticket holders promoting the sale of playoff tickets featured a photo of Lin jumping in celebration.

Lin did not formally announce that he would be out for six weeks until Saturday, March 31.

Additionally, last Friday, about an hour after coach Mike Woodson hinted Lin may be done for the remainder of the regular season—he told reporters he didn’t know “when” or “if” Lin would be back—the Knicks media relations staff released a statement contradicting the coach, the Daily News notes. The statement suggested there was a chance Lin would play either this Tuesday in Indiana or Thursday in Orlando. And while Lin, according to the Daily News, had not yet decided to have surgery, it was clear that Lin’s knee was more than just “sore,” as the team claimed, and that he was leaning toward surgery.

But Lin’s six-week timetable could be shortened “depending on the level of arthritis surgeons discover,” The New York Post reports.

“If they don’t see anything else wrong in surgery, just see the tear, typically you can get back in the NFL in two to four weeks and I’ve seen NBA players get back within that period,’’ Dr. Wellington Hsu, an orthopedic surgeon/assistant professor at Northwestern, told The Post. “That’s assuming there are no surprises."

Woodson said Lin's time frame “depends on rehab and how quickly he responds to the surgery. That’s something down the road that we just have to wait and see. Once they go in there and get it done, he could respond very quickly, at least I’m hoping, anyway.”
